Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the relationship to velocity?Velocity is the time rate of change of displacement: \(\vec{v} = d\vec{r}/dt\)
2. How is displacement different from distance?Distance is the total length of the path traveled, while displacement is the straight‑line change in position. If you walk back to where you started, your displacement is zero even though the distance is not.
3. Why do scientists use displacement vectors?They help describe motion, calculate speeds, and guide things like GPS, robots, and video games, making sure we know exactly where things are.

Position Vector: A vector from the origin of a coordinate system to a specific point in space.
Vector Addition: The process of combining two or more vectors to find a resultant vector representing their combined effect.
Reference Frame: A coordinate system used to describe the position and motion of an object.
